Anyone Have a Strange Voting Experience?

Here is mine. When I got to the precinct list my name wasnt on it and I was asked to fill out a “inactive voter” affidavit and show ID. I was then given a ballot and was able to put it in the machine like always BUT …

What the he** is an “inactive voter” list and why was I on it since I hadnt missed a vote inclusing primaries and special election sice at least the 80s?
